Russ talked with me at MMW in St. Louis. I was glad to here about his commitment with Callies and his new stroker package. We talked in great detail about the new strokers to come. I'm real comfortable with the 392 derived from a 6.1 block. It's the rod length to stroke ratio, plus the pancake sized piston and ring pack, that worries me about going to the 426. Same with taking the 5.7 to a 392. Just my .02

Bore size is 4.140" with a stroke length of 3.960" yielding 426 cubic inches.
The engine is running great, better than expected power output, no leaks, no problems at all. Thus far with conservative tune and only eight pounds of boost it is putting out close to 700 hp at the rear wheels. Car is being street driven to break in the engine. More boost will follow.

The 426 can be done without sleeves (we did it and Indy/Power Ported Performance did too). We have also taken the 5.7 to 392 and 370. We are looking to do a 383 as well. The rotating assembly for me 414 is getting balanced now and should be going in the truck soon!
It's good to see that more people are playing with the limits of the HEMI!

Beast, I truely believe that without a sleeved 426, it's a short lived hurrah. Sonic check these blocks once, and you'll agree. Your 414 is about the limit we would build without sleeves. At $3700, is it worth the extra 12 cu in?
